ABS Capital meeting conference room

For nearly 30 years, we've been helping growth companies reach their full potential.

At ABS Capital, our most productive partnerships begin with those who have successfully piloted their companies through these exciting first stages and are now determined to make the choices that will drive them further forward.

Many successful CEOs began their companies with a bold idea, or a better way — bent on delivering game-changing impact within their industries.

The skills, actions, and insights that may have served them best at the start may now be evolving in this next stage of growth, and ABS Capital can serve as a guiding partner through this time.

We deliver years of personal experience in the same fields where we invest most: business and tech-enabled services, and health care. We specifically focus on the dreams and realities associated with helming a company beyond its initial growth spurt. After all, we’ve faced these challenges and opportunities ourselves.

So we carefully choose the companies and CEOs we partner with, just as we expect them to carefully choose us. And once we’ve decided to work together, we prioritize growth potential above all and seek to build enduring value. The goal is to unleash the most potential for lasting growth.

After nearly 30 years, we still find this to be the best measure of success.

ABS Capital. Here, we grow.

Our Definition of Growth

Growth can be defined in many ways and found in multiple places. It’s never too early to talk with us.

If we had a “typical” deal at ABS Capital, this is what it would look like:

Our passion for company building began long ago and still lives on today.

In 1800, Irish linen merchant Alexander Brown (Alex for short) immigrated to America, settling in Baltimore. Soon thereafter he founded Alex. Brown & Sons, Incorporated, the first investment bank in the United States. Within ten years, they organized the first American IPO of Baltimore Water Company; this forever changed the growth trajectory of company formation.

For over a century, Alex. Brown & Sons, Incorporated continued to thrive and to help build the businesses that helped build America.

Flash forward to 1970, when Don Hebb joined Alex. Brown & Sons.

He knew this largely regional bank needed to be smarter and to work harder in order to compete with larger Wall Street firms. Don was the principal architect of Alex. Brown’s innovative, industry-focused investment banking units that sought to identify emerging trends and find the young companies poised to ride those waves. Alex. Brown led IPOs for game-changing companies such as Amazon, Microsoft, and Starbucks. Focusing on fast growth, capital hungry companies in new sectors and groups became the firm’s hallmark and brought it to a position of national prominence among Wall Street investment banks. Don rose to be the CEO of Alex. Brown and took the firm public in 1988.

After stepping down as CEO, Don then founded ABS Capital with a commitment of $20 million from Alex. Brown’s balance sheet. In just a few short years, he and founding partner Tim Weglicki had built such an impressive track record that they could raise their first outside fund — establishing ABS Capital as an independent firm. Prior to founding ABS, Don and Tim were successful in attracting and fostering talented professionals, and as ABS Capital’s investment opportunities grew and the number of active funds increased, they were joined by former colleagues and skilled operators of growth companies with which they had been involved.

At ABS Capital, the spirit that brought Alex. Brown to prominence and success lives on in a tightly knit, well-run, and highly-focused machine. Partnerships and investments developed at ABS Capital often lead to further partnerships and investments, as executives choose to return to the ABS Capital family.

While ABS Capital searches throughout the United States for the best growth companies, we remain committed to the city that gave us our start.

We love Baltimore and take great pleasure in giving back to the place that has given us so much.

Baltimore continues to embrace many of the opportunities in today’s world in areas of technology, biotech, education, and health care. But like so many cities, it is also confronting serious challenges. So beyond the charitable giving and community boards in which so many of us participate, we have made it a priority to consistently devote time and resources to helping Baltimore seize a brighter future.

Recent efforts include:

  • Mentoring children from Patterson Park Charter School through a Beyond School Walls program associated with Big Brothers Big Sisters
  • Partnering with BLocal, a commitment by Baltimore-area businesses to leverage our collective influence to help strengthen the city and create opportunities for Baltimoreans
  • Hiring summer interns through YouthWorks, Baltimore City’s summer jobs program
  • Volunteering time and donating healthy foods to Maryland Food Bank
  • Participating in winter coat and toy drives for Paul’s Place, a provider of programs, services, and support to strengthen individuals and families; fostering hope, personal dignity, and growth in Southwest Baltimore
  • Participating in collection of essential items for the Ulman Foundation‘s Ulman House, which provides free housing for young adult cancer patients, and their caregivers.
